Hyderabad-based Biological E has begun clinical trials of next-generation Covid vaccine to combat the XBB1.5 variant of the Sars-CoV-2 virus and expects preliminary results in June.
A Subject Expert Committee (SEC) last month recommended granting permission to the Pune-based Serum Institute of India (SII) for an Omicron XBB1.5 variant-based Covid-19 vaccine, with a local clinical trial waiver for emergency use.
Currently, India does not have any XBB 1.5 variant-based vaccines available.
"None of the vaccines available are protective against the currently circulating Covid-19 strains or those likely to emerge. On the other hand, the Omicron group has turned out to be mild, requiring no protection. Omicron also imparts good immunity against Covid19," senior epidemiologist Jayaprakash Muliyil Business Standard.
told These new-generation vaccines align with the World Health Organisation (WHO) guidelines, which recommended a monovalent XBB1.5 antigen composition for the Covid vaccine antigen in December. The WHO said the SARS-CoV-2 virus continued to evolve with important genetic and antigenic changes in the spike protein.
